Utilize rotary actuator 11 to make rotating shaft A14 rotation, then the equipment gear 65 that connected of rotating shaft A14 also rotates, and the gear C 66 of the driving gear 17 that equipment gear 65 is engaged also rotates.The rotation of gear C 66 is directly passed to the gear D 67 of coaxial connection, thereby gear D 67 only rotates equal angular with gear C 66, and makes driven gear 16 rotations via Timing Belt 64.Through the rotation of driven gear 16, transfer valve 34 rotations that the rotating shaft B15 of driven gear 16 is connected.
Action when switching to transfer valve 34 is elaborated.
In the present embodiment, the gear C 66 of driving gear 17 has 60 teeth, and gear D 67 has 40 teeth.In addition, equipment gear 65 has 30 teeth, and driven gear 16 has 40 teeth.
The transfer valve 34 of present embodiment needs positive and negative half-twist.The number of teeth of the driven gear 16 that Timing Belt 64 is engaged and the gear D 67 of driving gear 17 is 40 teeth, thereby for making driven gear 16 half-twists, gear D 67 also must half-twist.Here because gear C 66 is the state of equal angular rotation with gear D 67 and fixes, thereby when making gear D 67 half-twists, also make gear C 66 half-twists.Because gear C 66 has 60 teeth, thereby the number of teeth of 90 ° of revolutions is 15 teeth.So, for making gear C 66 half-twists, must make the number of teeth of equipment gear 65 rotations 15 teeth that engage with gear C 66.That is, make equipment gear 65 positive and negative Rotate 180s ° through rotary actuator 11, and make transfer valve 34 positive and negative half-twists.Like this, driving gear 17 is made up of gear than different gear C 66 and gear D 67, and transmits the driving force of rotary actuators 11 via equipment gear 65,1/2nd driving forces of device that can embodiment 1 make transfer valve 34 rotations.
The driving force of general small-sized rotary actuator a little less than, but if according to the structure of present embodiment,, still can drive transfer valve fully, thereby Practical significance is quite big even if use the more weak rotary actuator of driving force.
On the other hand, be less than the structure of gear D 67, also can make transfer valve 34 rotation at a high speed through the number of teeth of gear C 66.Through adjusting the gear ratio, can the balance of driving force and rotary speed be adjusted to the best according to the device specification.
In addition, about driven gear 16, be connected in the structure of transfer valve 34 similarly through equipment gear, and can adjust driving force and rotary speed.
The device of present embodiment utilizes equipment gear 65 and changes the gear ratio, and transfer valve 34 is rotated with bigger power swimmingly, or rotation more at high speed.
In addition, through using equipment gear 65, and transverse width that can enlarged base 1 face side, and can adjust driving force and rotary speed.Simultaneously, because the width of Timing Belt 64 is narrower than chain, thereby can dwindle the space that constitutes driving section 50.Thereby, can make the transverse width w of base 1 face side become narrow, it is littler that the device integral width is become.
In addition, because Timing Belt 64 has elasticity, thereby can absorb the machining accuracy of formation driving section members such as gear and the error more or less of position is set.That is, but the elastic force absorption errors through Timing Belt 64 etc., thereby if more or less situations such as error occurring still is unlikely and hinders action, thereby the manufacturing of device is tending towards easily, significantly reduce cost.In addition, because Timing Belt 64 is lighter than chain, thereby the loss during power transmission is less, but the response of lifting device.
